The average temperature in Korea has increased by 1.5℃ over the last 100 years, the winter season has become shorter with a longer summer season, and the time for the blooming of spring flowers has become earlier due to global warning. As a result of these changes, agricultural productivity has decreased, the cultivation regions for crops have moved northward, and damages from winter pests has increased. Scientific diagnosis and evaluation of climate change is very important in setting a vision for future farming and the direction for agricultural policy. It will provide useful information for the establishment of countermeasures such as long-term regional agricultural development plans and farm household planning.
